A shorter barrel isn't going to make much of a difference in for twist rate requirements. Your standard 1:8 twist rate is what I would go with unless you want to do something funky like shoot subsonic bullets.

You may laugh, but I'm working tailoring the twist rate on my 308 Win build to stabilize 250gr subsonic. That requires a 1:8 twist to marginally stabilize the long heavy bullet, but a 1:7 twist looks preferable. (Tangent over)

QuickLOAD predicts that a 130gr Hornady ELD-M will reach ~2450fps from a 14.5in barrel. The load out of a 24in barrel according to Hodgdon Reloading data will produce ~2700 to 2800fps depending on the load. That is roughly ~25 to 35fps per inch.

So when looking at factory loads, the velocity data will before a 24in barrel. If you subtract roughly 25-35fps per inch, you'll probably fall in the neighborhood of what you'll see from your rifle.

Hopefully this gives you a good idea of what to expect. Keep us posted!
